LFR251001CID Application Field and Working Principle

LFR251001CID, classified as a type of fuseholder, is a product manufactured by AC/DC Electronics, currently sold in the electronic market. It is a dual-circuit fuseholder designed for 30A/600V two-circuit protection. It is a thermal-magnetic circuit protection solution with UL and CSA recognition, UL 4248-20 and CSA C22.2 No. 5.4 listed.

Application Field

The LFR251001CID fuseholder can be utilized for electrical equipment requiring dual-circuit protection. It is the ideal protection solution for systems that are subject to higher currents, lower voltages, and repetitive overloads. Examples of such systems include office equipment, household appliances, and industrial products.

In particular, the LFR251001CID fuseholder is suited for use in a variety of applications, such as data centers, medical facilities, and telecommunications equipment. It also fits well as a current-limiting device in high-inrush circuits that require circuit protection with a fast response time.

Working Principle

The LFR251001CID fuseholder is a thermal-magnetic circuit protection solution. It consists of two 20A/600V thermal-magnetic fuses connected in series, with a single 30A/600V fuse mounted on the front panel for circuit breaker function. The two thermal-magnetic fuses are designed to operate together with a single fuse to provide circuit protection with fast response time.

The two thermal-magnetic fuses act as the primary elements in protecting against overcurrent conditions. The single 30A/600V fuse provides additional protection on the front panel against short-circuit faults, providing low-level protection at higher currents. The source of power is then sent to the fuseholder through the thermal-magnetic fuses. If an overload occurs, then the two thermal-magnetic fuses will open before the single 30A/600V fuse, preventing damage to the system.

The thermal-magnetic fuses are designed with overload and reverse current protection. This design ensures that even if a short-circuit occurs, the circuit will be shut down before the two thermal-magnetic fuses are completely melted. This provides efficient protection from severe overloads or short-circuit faults.

Conclusion

The LFR251001CID fuseholder is an effective thermal-magnetic circuit protection solution for electrical systems requiring higher currents at lower voltages. It is suitable for a variety of applications, such as data centers, medical facilities, and telecommunications equipment. The two 20A/600V thermal-magnetic fuses with a single fuse provide fast response to overcurrents and short-circuit faults. This ensures maximum system protection from overloads and short-circuiting.
